Abstract

The proportioner (10) has a variable speed controlled DC motor (12) having a gearbox (14) and crankshaft (16) at either end which are connected to reciprocating piston pumps (18). The outputs (18a) of the two pumps (18) are fed to a manifold (22) where the pressure of each output is measured. The user sets a setpoint pressure (e.g. 1000 psi) and the controller (26) then compares the pressures of the two components and controls the higher of the two relative to the setpoint. Ratio assurance is monitored by continuing to look at both output pressures. If one side falls below a predetermined percentage of the setpoint (50% in the preferred embodiment), an alarm may be raised or operation stopped.

快速设定材料配合加料器Quickly set the material with the feeder

技术领域technical field

本申请要求2002年11月1日提交的美国申请序列号60/423,342的权益。This application claims the benefit of US Application Serial No. 60/423,342, filed November 1,2002.

背景技术Background technique

大家已经熟知用于材料(例如聚脲(polyureas)和其他泡沫)混合的多种成分的配合加料器。这类设备通常具有简单的机械式配合加料器，要不然就具有复杂并笨重的液压驱动的单元。虽然例如美国专利号3,196,802中所述的电子操作的单元，已经被用于按比例分配多种成分材料，但是这类设备并不是设计用于快速设定上述类型的材料，这不仅需要比例的精确控制，而且需要压力的精确控制。Multi-component compound feeders for mixing materials such as polyureas and other foams are well known. Such equipment typically has simple mechanical compound feeders or else complex and cumbersome hydraulically driven units. While electronically operated units, such as those described in U.S. Patent No. 3,196,802, have been used to proportion multiple component materials, such devices are not designed for rapid setting of the above types of materials, which requires not only proportional precision control, and requires precise control of pressure.

发明内容Contents of the invention

因此本发明的一个目的是提供一种电动的配合加料器，它可以被简单地制造并使用，容易运输并能够精确计量两种成分。It is therefore an object of the present invention to provide an electric compound feeder which is simple to manufacture and use, easy to transport and capable of precise metering of two components.

为此，该配合加料器具有一个可变速控制的直流电机，该直流电机在每一端具有一个变速箱和曲轴，所述变速箱和曲轴连接到往复活塞式泵。这种电机、变速器和曲柄用在例如由本发明的受让人以ULTRA商标销售的电动真空喷漆机中是人们所熟知的。这两个泵的输出都供给到一个歧管，在该歧管处测量每个输出的压力。用户设定一个设定点压力(例如，1000psi)，然后控制器比较第一成分和第二成分(通常指定为催化剂或成分A和树脂或成分B)的压力并相对所述设定点控制两个压力中较高的一个。目前大多数材料设计为1∶1的比例，也就是说，每种成分是等量的。由于粘度和温度的变化，即使抽取等量的每种成分(用于在喷枪或其它涂漆机混合)，压力也可能一边比另一边高。因此控制器连续地比较压力并将较高的一边调节到设定点。To this end, the compound feeder has a variable speed controlled DC motor with a gearbox and crankshaft at each end connected to a reciprocating piston pump. Such motors, transmissions and cranks are well known for use in electric vacuum sprayers such as those sold under the ULTRA trademark by the assignee of the present invention. The outputs of both pumps are fed to a manifold where the pressure of each output is measured. The user sets a set point pressure (eg, 1000 psi), the controller then compares the pressures of the first and second components (typically designated as catalyst or component A and resin or component B) and controls the two relative to the set point. the higher of the two pressures. Most current materials are designed in a 1:1 ratio, that is, equal amounts of each component. Due to changes in viscosity and temperature, even when pumping equal amounts of each component (for mixing at a spray gun or other paint machine), the pressure may be higher on one side than the other. So the controller continuously compares the pressure and adjusts the higher side to the set point.

比例保证是通过连续观察两个输出压力而被监控。如果一边的压力下降到设定点的预定百分比(在优选实施例中为50％)之下，那么警报就可能出现或者操作被停止。当然这个阈值百分比可以变化。Proportional assurance is monitored by continuously observing both output pressures. If the pressure on one side drops below a predetermined percentage (50% in the preferred embodiment) of the set point, then an alarm may occur or operation may be halted. Of course this threshold percentage can vary.

本发明的这些和其他的目的和优点将从下面结合附图的描述中变得更清楚，附图中相同的标记指示几个视图中相同或相似的部件。These and other objects and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings, in which like numerals indicate like or like parts throughout the several views.

附图说明Description of drawings

图1是本发明配合加料器的前视图。Figure 1 is a front view of the compound feeder of the present invention.

图2是本发明配合加料器的后视图。Figure 2 is a rear view of the compound feeder of the present invention.

具体实施方式Detailed ways

本发明的配合加料器如图1和2所示，总的指示为10。为此，配合加料器10具有一个可变速控制的直流电机12，该直流电机12在每一端具有一个变速箱14和曲轴16，所述变速箱和曲轴连接到往复活塞式泵18。这种电机、变速器和曲柄用在例如由本发明的受让人以ULTRA商标销售的电动真空喷漆机中是人们所熟知的。这两个泵18的输出18a都供给到加热器20，从而被供给到歧管22，在该歧管用压力传感器24测量每个输出的压力。The compound feeder of the present invention is shown generally at 10 in FIGS. 1 and 2 . To this end, the compound feeder 10 has a variable speed controlled DC motor 12 with a gearbox 14 and crankshaft 16 at each end connected to a reciprocating piston pump 18 . Such motors, transmissions and cranks are well known for use in electric vacuum sprayers such as those sold under the ULTRA trademark by the assignee of the present invention. The outputs 18a of both pumps 18 are fed to a heater 20 and thus to a manifold 22 where the pressure of each output is measured with a pressure sensor 24 .

用户设定一个设定点压力(例如1000psi)，然后控制器26比较两个成分的压力并相对所述设定点控制两个中较高的一个。直流电机控制为美国专利号4,397,610中所示的那种类型，该专利的内容被包含于本文中。The user sets a set point pressure (eg, 1000 psi), then controller 26 compares the pressures of the two components and controls the higher of the two relative to the set point. The DC motor control is of the type shown in US Patent No. 4,397,610, the contents of which are incorporated herein.

目前大多数材料设计为1∶1的比例，也就是说，每种成分是等量的。由于粘度和温度的变化，即使抽取等量的每种成分(用于在喷枪或其它涂漆机混合)，压力也可能一边比另一边高。因此控制器26连续地比较压力并将较高的一边调节到设定点。Most current materials are designed in a 1:1 ratio, that is, equal amounts of each component. Due to changes in viscosity and temperature, even when pumping equal amounts of each component (for mixing at a spray gun or other paint machine), the pressure may be higher on one side than the other. The controller 26 therefore continuously compares the pressures and adjusts the higher side to the set point.

比例保证是通过连续观察两个输出压力而被监控。如果一边的压力下降到设定点的预定百分比(在优选实施例中为50％)之下，那么警报就可能出现或者操作被停止。Proportional assurance is monitored by continuously observing both output pressures. If the pressure on one side drops below a predetermined percentage (50% in the preferred embodiment) of the set point, then an alarm may occur or operation may be halted.

可以想到，在不脱离由权利要求书所确定的本发明的精神和范围的情况下，可以对所述配合加料器进行各种改变和修改。It is contemplated that various changes and modifications may be made to the compounding feeder without departing from the spirit and scope of the invention as defined by the claims.
